I do agree with Xalener that it would be a nice addition. It's already nice to use Anim8or for some game models because of its simplicity. And if I could use it in combination with Zbrush or mudbox to create new generational game characters or objects normal maps would definitely come in handy. It doesn't seem like it would be too much work either since the system is already built in, though I can't be sure of that of course
